We have just been notified by one of our vendors that we must comply with the Sunrise 2005 Structure by January 1, 2005
This means that the current UPC code field in item setup must accommodate up to 14 digits ??? ???

the following is part of the email received:
-----------------------------------------------------------------------
• We will be prepared to accept inbound EDI Invoices  
using a 12, 13, or 14-digit structure.  
• Data structures that are less than 13-digits will be right justified and left zero padded.  
The structure on our EDI Purchase Orders will be as follows:  
Sunrise 2005 Structure   Number Example     EDI Format  
UCC-12 (U.P.C. – A)       614141005277   061414100527  
 
EAN/UCC-13               3439494949392  3439494949392  
-----------------------------------------------------------------------
 
Does above make any sense to anyone?

You are quite correct. We are actually importing a description that comprises SKU and UPC code that comes from a cross reference table (Access). The incoming EDI PO item line is compared with that external cross reference. So it looks like we do not really have to worry about anything else but to update this external table.
 
Thanks for your input
